Ok, So I got the new 436 yesterday, I downloaded sentinel and programmed my favorites lists into it using quick keys. But with the MARCS IP systems, It will not let me use the assigned quick keys for some reason. They do not show up in the scanner while I am trying to scan, the only way i receive them is if I use the Zipcode feature. I also have a a problem with scanning display... I was playing around with the buttons when I got the display in some sort of three tiered system which I am unable to figure out how to get out of... any help would be awesome. In the picure you can see how the quick keys are still not showing up... I tried to follow the sentinel video that scannermaster has on their site, but i think i somehow messed it up. Thanks!
